There is no direct relation between volts and BTU.
12,000 Btu is 4.7hp
18000 BTU means TON 1.5 ,12000 BTU means 1 TON
12000
12000BTU is 4.7hp
650 sft multiplied by 26 which means 16900. I BTU =12000 Divide 16900/12000 = 1.4 ton
12000 per hour
usually 20 btu's per square foot so......12000 btu's should do fine
12000 btu = 1 ton 1 ton per 400 sq ft 1200 / 400 = 3 3 times 12000 = 36000 btu
11800 BTU/hr is 3.46kW
12000 BTU is equivalent to approximately 3.51 kVA.
12000 btu/min
Btu and cubic meter are two different measuring units. Btu is the unit for heat transmission, like in ac units 12000 btu/hr. It means this ac unit would remove 12000 btu of heat from the room in one hour. where as cubic meter is the unit for volume.
